Application

The very compact TQ/ TC are especially designed for connection to digital

measurement systems. All TC /TQ are supplied with colour coded leads se-

condary leads. Correct closing of the current transformer/sensor is guaran-

teed by a distinct sound of a “click”. Two UV-resistant ty-raps are supplied

with the current transformer whicn can be easily mounted around the pri-

mary conductor.

All TC18/ TQ42 and TQ84 current transformers are capable of supplying

the specified burden at the end of the secondary leads. The accuracy of

these current transformers (TQ42/TQ84) results in highly accurate measu-

rement.

All TQ18-B current sensors and all TQ27 current transformers are capable

or supplying a burden of 0.2 VA at the end of the cable. The accuracy class

1 for all these CT’s are perfect for high accurate kWh measurements.
